Mark - my copy of the Snakes & Arrows album in 5.1 came while I was traveling this week and I'm now sitting back in my theater enjoying it.

It is a very nice audio mix. The surround sound is blended very well to the point of not being distinctly noticeable save for the feeling of immersion you have while listening to the tracks. It's a nice addition to my library, especially having picked it up used off Amazon for the price of what the CD probably cost originally.
